direction toward the central web. A bolt 14 is carried b thebar 8 and thumb-nuts 15 and 16 carrie ,by said'bolt bearing against the outer faces of the plates 9 and 11, respectively, limit the inward movement of the lower ends of the plates toward the web. The uncurling plates 9 and 11 project forwardly in the line of feed, as clearly shown in Fig. 1, and cod crate with the forwardly projecting part 1 on. the centralweb of the bar 8. A pin 18, carried by the central web, projects from each side thereof and ex-' tends through openings in the uncurling es the plates plates 9 and 11. This pin 9 and 11 and also revents fabric from creeping up too big between the plates.

T e bar 8 is pivoted at 19 to a supporting head 20. This supporting head 20 is clamped to a plate 2l which in turn is mounted on a bracket 22 bolted to the main casing of the machine.- The plate 21 is a right angle late and the horizontal member 23 thereof is provided with slots, through which screws 24 ass. These screws 24 extend into the brac et 22 and serve to adjustablyhold the plate 21- on the bracket. The slots are so formed that the plate 21 may be moved longitudinally of the upper open end of the bracket 22, and this movement of the plate 21 will move the fabric guiding tially at right angles to the plane of travel the main casing by clamping screws 25. These screws pass through slots 25 in the bracket soithat said bracket may be adjusted vertically on'the screws and this vertical adjustment of the bracket raises and lowers the fabric guiding and uncurling device and permits the edges of the fabric being stitched to project more or less above the feed wheels. This adjustment of the fabric guide and the edge of the fabric increases or decreases the width of the overseam. V

The bar 8 is loosely mounted on the supporting head 20 and swings by gravity to the position shown in Fig. 1. In this position, the rear edge of the bar rests against an adjustable bolt 26 which is carried by a bracket 27 attached to the supporting head 20.

This bracket has spaced walls 28 and 29 between which the bar rests against the end of the adjustable bolt. The feed of the fabric also draws the bar against this bolt. By adjusting the bolt, the position ofthe fabric guide and uncurling device relative to the stitching point may be varied. It is desirable that this ,fabric guiding or uncurling device shall as close to the stitching point as possible without interfering with the.

free fccd'jof the fabric by the feed wheels. I

It will be obvious that when a bee and uncurling device must be positioned a greater distance from the stitching point.

The bracket 22 is secured to .parent that I have an adjustable bolt extendin fabric is being stitched the fabric guiding Lasagna This can be readily accomplished by adjusting the bolt above described. W en a thicker fabric-is being stitched, the fabric guiding and uncurling device must also be and uncurling device in inoperative posh tion.

A spring 32 normally forces the latch into contact with the supporting head 20.

In ordcr'to facilitate the ad'ust'ment of the bracket 22, I have provide an adjusting screw 33 which is threaded into the casing 4 and is provided with a groove in its head to receive a lug 34 carried by the bracket 22. This screw turns freely in the lug'34 and by turning the screw in one direction after loosening the clamping screws 25, the bracket may .be ad'usted to raise the guide, and by turni t e screw in the other direction it may lowered. In a device where the adjustment is vertical, this adjusting screw isof considerable 'importance as otherwise when the clampin screws 25 are released the bracket woul drop by gravity. Then a in, this adjusting screw enables fine a justments to be made which-are desirable.

From the above description, it will be aprovided a fabric guidmg and uncurling evice which is so su ported that it. may be readily and quick y adjusted. to position the same for operating upon different thicknesses of fabric and for also increasing or decreasing the depth of the overseam.

Having thus described my invention, what I claim is:

' 1. The combination with supporting feed wheels, of a fabric guide for iiding the fabric to the feed wheels, said abric ide comprising a central bar having a we extending between the layers of the fabric, uncurling plates carried by said central bar and engaging the outer faces of said layers of fabric, and means for supporting said fabric guide including a supporting head, a bracket carried by said supportin head having spaced walls between which t e center bar of the fabric guide rests when said guide is in normal operativeposition, and between said spaced walls and against which said her of V the fabric guide rests. v
